I think it was right after Ralph got drunk and threw up all over the bed at Howard's house. Ralph called in and they started arguing. Ralph said Howard changed. He was now "Mr. Hamptons, man about town."

Maybe hes being treated for an std and the wig is afraid he might somehow get contaminated if he associates with his long time butt buddy? It is odd though, that big mouth had a comment on any and everything and gave it endlessly no matter if anyone wanted to hear it or not. But, like robins illness, ralphie-poos vanishing will be seldom if never discussed openly.

R-R-R-Ralph is a .... a .... 43-year-old berry-faced.... is a 43-year-old.... R-R-R-Ralph is a berry-faced ..... a 43-year-old berry-faced.... quee...quee....quee....RALPH IS A 43-year-old b-b-b-berry-faced queer!

Like most regular callers like Bobo, Ralph had a need to be on the air, now that he has a show, that need is fulfilled. Obviously he doesn't really give a shit about Howard's show. In a way the listeners win as we can choose not to listen to his lame show and there is no fear of him ever coming on Howard's show.
